Abstract
The utility model discloses a pre-stress U-shaped sheet pile. A pile body structure is in a U-shaped section type, and a pile body structurally comprises concrete and at least one group of steel bar cage; the steel bar cage is formed by U-shaped folding line type hoop bars and vertical pre-stress main bars; the two ends of the steel bar cage are connected with a metal end plate; and the metal end plate is in a section type which is the same as the cross section of the pile body. The cross section of the pile body has eight stress eliminating circular-arc angles, and the radius of the circular arc of each angle is 0.06m to 0.12m; and at least four pre-stress main bars are located at the circular centers of the stress eliminating circular arcs of the angles. According to the plate pile disclosed by the utility model, angle damages can be effectively reduced in a piling process, so that the wholeness and the integrity of the pile body are improved, and the anti-bending and anti-shearing capabilities of the pile body can be improved.
Description
Technical field
The utility model relates to a kind of retaining soil of field of civil engineering, bank protection reinforced concrete structure, specially refers to a kind of U type prestressing force sheet pile.
Background technology
In construction work, unit bulk head water retaining directly bears horizontal loads, and the common structural form has gravity dam, high-pressure rotary jet grouting pile, steel sheet pile, SMW stake, cast-in-place diaphragm wall, cast-in-place bored pile, steel concrete gravity barricade etc.
Traditional soil-baffling structure is main with cast-in-place or field fabrication mostly, need bigger construction plant and long curing time, and the structural shape surface is straight, does not have characteristics attractive in appearance.
The prefabricated sheet pile that minority is used, in squeezing into process often because the impact of pile monkey is prone to produce the crack or the bight is damaged, thereby influence attractive in appearancely, even influence the stress performance of structure.
In sum, to the defective of prior art, need the stake of a kind of Prestressed U template especially, with the problem of mentioning more than solving.
The utility model content
The purpose of the utility model is to provide the stake of a kind of Prestressed U template, through the employing special structural design, thus the purpose of realization the utility model.
The technical problem that the utility model solved can adopt following technical scheme to realize:
U type cross section type structure design is adopted in the stake of a kind of Prestressed U template, comprises concrete and at least one group of reinforcing cage; Said reinforcing cage is made up of U type broken line type stirrup and vertical prestressing master muscle; The two ends of said reinforcing cage are connected with metal end plate, it is characterized in that, said pile body cross section has 8 stress and eliminates arc chord angle; Arc radius is 0.06m～0.12m, wherein has at least 4 said prestressing force master muscle to be positioned at the center of circle that described stress is eliminated arc chord angle.
In an embodiment of the utility model, said U type broken line type stirrup in broken line bending process with prestressing force master muscle for being welded to connect.
In an embodiment of the utility model, respectively there is a metal end plate at the pile body two ends, and the cross sectional shape of said end plate is identical with said pile body cross sectional shape.
The U template stake that the utility model provided; Adopted broken line type U type stirrup, the pile body cross section is provided with 8 stress and eliminates circular arc, and home position is provided with prestressing force master muscle; Make in the piling process; Eliminated the stress concentration phenomenon at stake angle, pile quality is more reliable, and the stake of said U template has better opposing horizontal loading ability.
Description of drawings
Fig. 1 is the Prestressed U template stake front schematic view of a specific embodiment of the utility model.
Fig. 2 is the structural representation of the said Prestressed U template of the utility model stake.
Fig. 3 is the sectional schematic diagram of the said Prestressed U template of the utility model stake.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, below in conjunction with the specific embodiment, further set forth the utility model.
Like Fig. 1, Fig. 2 and shown in Figure 3, the stake of the described Prestressed U template of the utility model comprises that cross section is the shape body of U type; Said pile body has a reinforcing cage 1 and a whole concrete bodies 2 at least, and said concrete 2 is formed at after reinforcing cage 1 formation, after Vibration Technology; Promptly form concrete 2, said reinforcing cage 1 two ends, each connects a kind of metal end plate 3; Said concrete bodies 2 has 8 stress and eliminates circular arc; The stake aperature of angle phenomenon when existence of this circular arc can effectively prevent to drive piles, it is concentrated to eliminate stress, and makes pile quality better and more attractive in appearance.
Said reinforcing cage 1 has a plurality of prestressing force master muscle 11 and stirrup 12, and said stirrup 12 is continuous broken line shape, and is welded on the prestressing force master muscle 11, and said broken line type stirrup 12 makes the stake of said Prestressed U template have better shearing resistance, torsional property.Said prestressing force master muscle has at least 4 to be positioned on the said stress elimination circular arc center of circle.
In a concrete embodiment; The stake of described Prestressed U shaped steel reinforced concrete breast boards has a square precast assembly capping beam; Make described Prestressed U shaped steel reinforced concrete sheet pile after squeezing into the construction pile sinking; Better aesthetic is arranged, make that simultaneously the connection between the sheet pile is tightr, holistic resistant behavior is better.
In another concrete embodiment, said pile body 2 has 8 stress to eliminate circular arcs, and arc radius is 0.1m, has effectively eliminated the stress concentration phenomenon at stake angle, makes sheet pile that better pile body integrality arranged.
In another concrete embodiment; Said stirrup 12 and said metal end plate 3 are for being fixedly connected; Make said reinforcing cage 1 be connected more firmly like this, thereby strengthened the holistic resistant behavior of said Prestressed U shaped steel reinforced concrete breast boards stake with said metal end plate 3.
Though it will be appreciated by those skilled in the art that the utility model is to describe according to the mode of several embodiment, be not that each embodiment only comprises an independently technical scheme.Narration like this only is for the sake of clarity in the manual; Those skilled in the art should do manual as a wholely to understand, and regard technical scheme related among each embodiment as the mode that can be combined into different embodiment each other understand the protection domain of the utility model.
The above is merely the schematic specific embodiment of the utility model, is not in order to limit the scope of the utility model.Any those skilled in the art, revises and combines the equivalent variations of under the prerequisite of design that does not break away from the utility model and principle, being made, and all should belong to the scope that the utility model is protected.
More than show and described basic principle of the utility model and the advantage of principal character and the utility model.The technician of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the manual that the utility model just is described; Under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection domain to be defined by appending claims and equivalent thereof.
